Abstract: Societies faced serious environmental problems locally, regionally, nationally and
globally, this is due to the wasteful consumption of the world’s resources. All of that is already
having an impact on human health, on the economy and will affect the quality of life today
and for generations to come. Cities are the focal points and drivers of societal development in
all countries. They are responsible for a lot of significant environmental challenges, as they are
the largest consumers of natural resources and the biggest sources of pollution and greenhouse
gas emissions on the planet. Thus, there is a need for a big shift in designing our cities to
overcome all of these problems. Starting with the neighborhood design, which they are the
beginning of any changes in the cities. The actions and decisions taken on this level are in
need of integration with many variables such as design principles, technological solutions,
landscaping, transportation and infrastructure.
On the other hand, the rapid urbanization in Egypt is reflected in the increases in the
percentage of the total population which is not expected to slow down. To meet these demand
for housing, hundreds of integrated residential projects are being constructed all over Cairo‘s
desert through horizontal expansion to accommodate the increasing population by providing
new healthy cities for the new generation. But actually, with this expansion in designing new
integrated residential neighbourhoods, no regard was given towards the environmental impact.
Hence, the paper discusses the issue of planning future sustainable neighbourhood to reach the
sustainable development. It also evaluates the design principles that turn our integrated
residential neighbourhood to become self-sustain to reach the sustainable life for every
Egyptian citizen. Those principles are then used to evaluate a selected case study, which is one
of the best integrated residential projects in Cairo called AL Rehab. The results showed that
the selected case study do not fulfil most of the sustainable design principles from the
environmental side although it is socially and economically succeeded. This emphasizes the
necessity to develop design principles and update current urban planning regulations to
optimize sustainable urban configurations in the urban environment.

1. Introduction
According to the increase of the urban population all over the world which is expected
to reach 70% of the total population by 2050 (Shen, L. & Ochoa, J. & Shah, M. &
Zhang X., 2010). This rapid urbanization is responsible for leasing of valuable
ecosystems and lands for satisfying the urban needs. Moreover, this World’s
population will live in cities, which they are responsible for the wasteful consumption
of water, energy and other resources, with lack of appropriate infrastructure and
technology (Price, C. & Tsouros, A., 1996). So, if the current and future urban areas
continue with the same resource consumption practices without regarding the future
needs, serious environmental, social and economic problems are expected. Thus, the
challenge is to improve these problems of the existing cities, and makes the new cities
and the new integrated residential neighbourhoods more self -sufficient, and enjoyable
places to live. This means that, building new communities that are physically and
socially sustainable becomes a major challenge to resolve the nation’s housing crisis
and avoid repeating past mistakes. Hence, the governments should provide enough
sustainable homes to meet this growing demand, as good housing can improve our
social, environmental and economic well-being. Also they help in the creation of better
communities that can affect our health, our opportunities for happiness and can attract
investment. This means that the strategic housing decisions that the governments will
adopt on the next few years are critical to the life of the next generation (Department
for Communities and Local Government, 2007).
Hence, achieving sustainability in contemporary time will require a major paradigm
shift, essentially reversing traditional development, and changing our philosophies and
behaviors. Simultaneously, many cities around the world has developed their
sustainable urban development plans for leading their urbanization process towards a
desired status of urban sustainability (Shen, L. & Ochoa, J. & Shah, M. & Zhang X. ,
2010). Those plans apply the suitable design principles to achieve the goals of
sustainability. The focus mainly to improve the quality of life of citizens with the
requirements of modern life by taking into consideration minimizing their impact on
the environment.
1.1. Research Objective
The paper aims to achieve the criteria of designing a sustainable neighborhood in order
to reach a healthy life for everyone in Egypt by decreasing their effect on the
environment and also in line with the country's economy. As the housing sector is
critical to the Egyptian’s future, so the decisions the government will take today to
make a crucial difference to the lives of generations to come. Thus, evaluating the local
experience of establishing new integrated residential neighbourhoods is highly needed
to identify the design scenarios which clarify the future vision for the government in
order to achieve sustainable urban development.
1.2. Literature Review
To outline the principles of the sustainable neighbourhood, some of the literature has
been explored concerned with how to achieve the sustainability on the urban
neighbourhood level with the attempt to draw out some lessons. The literature review
has been investigated works done by researchers such as the findings reached by
(Lindström P.& Lundström M., 2008) in ‘ Sustainability by Sweden perspective on
urban Governance ’, and also the design principles of sustainable neighbourhood done
by (Kellett R.& Fryer S. & Budke I. , 2009)) in their studies on ‘Specification of
Indicators and Selection Methodology for a Potential Community Demonstration
Project- Vancouver’. In addition to that, other researcherss’ findings on the theoretical
ground of the sustainable neighbourhood such as (Talen E., Kochinsky J., 2010) in
‘Subsidized Housing in Sustainable Neighbourhoods’, and the contribution of the
sustainability indicators such as (Shen, L. & Ochoa, J. & Shah, M. & Zhang X., 2010)
‘The application of urban sustainability indicators ’. Also, other researchers have been
mentioned within the research that discussed the sustainability aspects of the urban
design for new cities such as (Shalaby,2000) and (Alqadi, 2013) findings on ‘Compact
Urban Form ’ and (Bayoumi M. & Fouad Y. & Roshdy K. , December 2007 )
findings on ‘ Egypt National Capacity Self-Assessment (NCSA) – National Strategy
and Action Plan for Capacity Development’.
1.3. Research Methodology
The purpose of this paper is to identify the design principles that address sustainability
issues with the broader aim of creating a model checklist to enhance sustainability in
the residential built environment. Hence, the research discusses the principles that help
to reach a sustainable neighbourhood development for the future generation. The
research mainly depends on analyzing a case study for “Al Rehab city “ which is one
of the largest and successful communities in our country in order to convert it to be
healthy sustainable neighbourhood. This discussion of the selected case study has been
set against the design principles of the sustainable neighbourhoods.
2. Why Sustainable Urban Development
The concept of the sustainable urban development plans in many cities around the
world has been developed for leading their urbanization process towards a desired
status of urban sustainability. This concept depends on the proper use of resources to
guarantee equity, protection of the natural environment, minimal use of non-renewable
resources, and economic diversity. Also to guarantee community self-reliance,
individual well-being, and satisfaction of basic human needs. According to that urban
sustainability is defined as “the challenge to solve both the problems experienced
within cities and the problems caused by cities”, recognizing that cities themselves
provide many potential solutions (Shen, L. & Ochoa, J. & Shah, M. & Zhang X.,
2010). This urban sustainability depends mainly on two terms, which are the terms
sustainability and sustainable development. Despite of the quite different meaning,
these terms are often erroneously used interchangeably. It is important to understand
the difference between them, and how the two concepts interact.
2.1. Sustainability
Sustainability is a term that can have different and often opposing meanings when
applied to economic, social and environmental situations. Sustainable definition shows
the linkage of three important spheres of life which are: social, economic, and
environmental health of our community, as shown in figure (1) (Meter, K., 1999). It is
a term that means that a person or society lives within the means of what the earth can
provide over a long term, and it can be carried out over and over without negative
effects on the environmental effects or high costs.
Figure (1): The three interlocking circles of sustainability

2.2. Sustainable Development
While sustainable development is a term that can be achieved by the adoption of
policies and programs to solve the global problems. It is the main concern for decision
makers, experts and planners at local, national and global levels. Recognizing that,
there is a well-known definition of sustainable development is taken from the
Bruntland Report which is "Sustainable development is development that meets the
needs of the present generation without compromising the ability of future generations
to meet their own needs"(World Commission on Environment and Development,
1987).
Thus, the sustainable urbanization refers to the well-balanced relationship between the
social, economic and environmental agents in society in order to accomplish
sustainable urban development. Which means that the terms “urban sustainability,
sustainable city and sustainable community” refer to the desirable state, while
“Sustainable urban development” refer to the process towards the desirable state (Shen,
L. & Ochoa, J. & Shah, M. & Zhang X., 2010).
2.3. Neighbourhood
Planning for sustainable urbanization, has started with designing the new integrated
residential neighbourhood which has a key role in promoting the future urban
sustainability and respond to the major trends in the world that affect in cities
especially in the developing world. Thus, researches over the past decades have
confirmed that integrated residential neighbourhood form can have a great impact on
the physical health, accessibility, crime, safety, and social interaction, in which all of
them are important aspects of achieving the quality of life in the neighborhood. So the
housing policy has become increasingly oriented towards ensuring residents to live in
what could be termed ‘‘Sustainable Neighbourhoods ’’ not only low in poverty and low
in crime, but walkable, transit served, and accessible to a wide variety of services and
facilities (Talen E., Kochinsky J., 2010).
2.3.1. Definition of Sustainable Neighbourhood
From here, the definition of sustainable communities is “meet the diverse needs of
existing and future residents, their children and other users, contribute to a high quality
of life and provide opportunity and choice. They achieve this in ways that make
effective use of natural resources, enhance the environment, promote social cohesion
and inclusion and strengthen economic prosperity”. These mean that the
neighbourhood is an ecosystem that it provides the essential local habitat for humans,
and should provide as far as possible for their comfort (Al- Hagla K., 2008).
Improving sustainability at a neighbourhood level contributes to more sustainable
environments at a wider scale. Therefore, given our large urban population, getting
neighbourhoods’ right is important both for the people who live in them and the
resources they consume. This means that neighbourhood sustainability is about how
buildings and the spaces around them work together and the impact they have on the
activities that take place there. As well as the functional aspects of buildings and
spaces, their design, quality and aesthetics all work together to shape the urban built
environment and influence local social and cultural identity. Implicit in these terms is
the understanding that a sustainable neighbourhood is more than the sum of its parts,
i.e., it is not just a string of sustainable houses, or a sustainable transport system, it’s
the combination of these and many other sustainability objectives across a
predetermined scale. Simultaneously, the results in how new communities can be
concluded under the following four themes: (Falk N. & Carley M., 2012).
• Healthier and stronger communities.
• Safer streets and living places.
• A greater choice of homes.
• Environmental features that add value to living in a new neighbourhood.
Simultaneously, to count an integrated residential neighbourhood to be as a sustainable
urban neighbourhood, it should have five basic ingredients as follows (Falk N. &
Carley M., 2012):
• It should have a wide choice of housing and facilities to ensure long-term value and
to create a balanced community over time. A neighbourhood with some common
facilities requires a minimum of between 500 and 1,000 units, with homes catering for
a range of incomes and ages.
• It is well connected to jobs and services by foot and bike as well as by other modes of
transport in order to cut travel time and costs. Creating connectivity (so that people do
not have to depend on their cars and can be economically active) requires a location on
a transport corridor or close to a town or city centre.
• It should have places of different character that appeal to different markets. Creating
character or a sense of place requires a minimum net density of 30 units to the hectare,
as in the garden cities and some of the new towns. Higher densities can support better
infrastructure but call for high-quality design.
• It is designed to save resources and ensure that neighborhoods are well looked after,
and do not ‘cost the earth’. Climate-proofing a development will include provision of
green infrastructure to promote biodiversity and reduce environmental impact, as well
as measures to save energy.
• It benefits from hands-on management and long-term stewardship by responsible
local organizations, such as housing associations, development trusts or parish
councils, both during development and after residents have moved in.
2.3.2. Sustainable Neighbourhood’s Themes
A sustainable neighbourhood is a form of a traditional neighbourhood, which meets the
same needs for housing, work places, and shopping, civic functions but in formats that
are compact, complete and connected, and ultimately more sustainable and satisfying
(Bodenschatz H. & Janke T., 2008). Hence, there are highly interdependent elements of
any sustainable urban design. Each corresponds to one of those basic systems that
support all the urban functions. These are: natural systems, land use systems, mobility,
energy systems, water management, material resources, waste management, and
affordable housing (McGeough U. & et al., 2004). According to that, we condensed the
sustainability measures of neighbourhood form into ten areas. All of those areas help the
urban form to reach a variety of goals related to sustainable urban places, which depend
mainly on the places that should be diverse, health-promoting, socially active, well
connected, safe, accessible, pedestrian-based, and not car-dependent, that in order to
improve the ability of place to sustain itself in the long term (Talen E., Kochinsky J.,
(2010). Simultaneously, to implement the urban sustainability certain policies should be
applied. Besides, good monitoring system should be used to evaluate their impact. This
means that, each government should choose its own indicators or its own sustainability
assessment tools to monitor and support their policies. The following part discusses the
design principle of each one of these systems and their interrelationships and provides a
range of tactical measures that can be taken to maximize their individual contributions
toward urban sustainability. Those ten themes are proposed below in table (1) to
categorize sustainability that focus on urban form (Kellett R.& Fryer S. & Budke I. ,
2009).
Table (1): Sustainable neighbourhood themes (Kellett R.& Fryer S. & Budke I. , 2009)
Them Definition
1. Land Sustainable neighbourhoods use land efficiently and dynamically to accommodate the
diverse places of dwelling, work, education and play vital to sustaining human
populations. Thus, that refers to the allocation and spatial arrangement of land and land
uses.
2. Mobility Refers to the degree to which people have access to jobs, services and activities.
Sustainable neighbourhoods should provide mode and route options for residents to move
easily between dwellings and places of work, learning, shopping and with less impact on
the environment.
3. Energy Refers to the demand, supply and distribution of energy to power machines, buildings
and vehicles. To reach more sustainable neighbourhoods, energy demand should be
reduced and increase opportunities to meet the demand with renewable energy and low
emission sources as well as efficient distribution systems should be used such as
community or district energy systems.
4. Housing Sustainable neighbourhoods should include an appropriate mix of housing types, sizes,
and density, resulting in diverse, safe and socially active places to live. This refers to the
affordability and diversity of the housing stock critical to a socially and economically
diverse society.
5. Natural Habitat Refers to the network of places, ecosystems that support the natural development of plant
and animal populations. Removing habitat has negative impacts on the balance of the
natural systems. So that, sustainable neighbourhoods protect, enhance or restore habitat
of sufficient quality, and quantity to support locally significant plant and animal species.
6.Water: It refers to the hydrologic cycle, including precipitation (rain, snow, hail), surface water
and ground water. To achieve more sustainable neighbourhoods carefully manage
consumption of potable water and treatment of wastewater to protect and restore the
natural hydrology cycle, including aquatic ecosystems.
7. Economy Refers to the interplay of jobs and commerce that contribute to the economic well-being
of a neighbourhood. More sustainable neighbourhoods build a healthy local economy on
a diversity of business and employment options adaptable to change.
8. Food Refers to access to secure, local food production. So it is important to that the
neighbourhood should support local food production, also should reduce dependence on
imported food and should reduce the amount of transportation energy used to distribute
food.
9. Waste It refers to using the organic waste in Pyrolysis process and converts it to energy.
Sustainable neighbourhoods can meet the annual energy demand by bio-gas energy
produced from both dry urban and agricultural waste in a compact Pyrolysis carbon
harvester.
10. Materials Sustainable neighbourhoods should promote the reuse and recycling of buildings and
materials to reduce demand and carefully consider the sources of materials and their life-
cycles. Thus, that refers to the inputs martials or the used materials that have a big effect
on the built environment in a neighbourhood.
3. Research Study Area
During the last decades, the population of the Middle East and North Africa (MENA)
region increased rapidly (Winckler O., 2005), which have a negative impact on the
wasteful consumption of water, energy and other resources and shortage of available
housing (Goell E. & El-Lahham N. & Hussen W. , 2009). This leads the government
to establish new cities to accommodate this population growth, they mainly want to
adapt to the high demand for housing occurring in Cairo (Shalaby, 2000). The main
target is to create new integrated residential neighbourhoods with new urban
environments that are more livable, organized and attractive. Those new urban
environments were planned in order to attract part of the overpopulation in existing
cities, and protect agricultural land (Goell E. & El-Lahham N. & Hussen W. , 2009).
But in fact, the government and the private sectors just take the direction to create the
new integrated residential neighbourhoods just for achieving business and financial
goal. Those neighbourhoods have become a place for doing business with millions of
vacuum housing rather than a place where communities live. As already many citizens
in the Egyptian communities were living under these kind of unsustainable conditions
(Goell E. & El-Lahham N. & Hussen W., 2009). Simultaneously, those communities
need to be developed according to more sustainable design principles. Thus, this part
introduces an analysis of the Egyptian experience in constructing new integrated
residential neighborhoods in the desert. The research evaluates a selected case study
which is Al Rehab city, in order to analyze the evolution of the experience aiming to
identify the positive and negative aspects and extract important outcomes.
3.1.1. The Goals Analysis
The choice was based on it being a role model of success of the social and economic
aspect, but there is a little debate is it succeed from the environmental aspect or not.
Thus the paper monitors the achievement of the environmental principles of a
sustainable neighbourhood through the design of Al Rehab, in order to be duplicated as
a model in many of the future urban communities. The analysis aims to outline a
criteria system for Egyptian Sustainable Neighbourhoods, in which the neighbourhood
could become fully sustainable with a minimum 50% reduction in the environmental
impact. The ability to achieve this goal depends on the principles of sustainable
neighbourhood, which are complex and contradict to each other.
3.1.2. Existing Conditions
Al Rehab city is a fully-fledged community. It is the first city built by the private sector
in Egypt having comprehensive services to cater for all needs of it’s residents. It is set
in an area of 10 million m2 in New Cairo to accommodate 200,000 inhabitants. It is
located ten minutes away from Heliopolis and Nasr City, on the Cairo Suez road, and
20 minutes from downtown Cairo, its site is well connected with the surrounding city
level, as shown in figure (2) (Talaat Moustafa Group, 2013).
Figure (2): Location of Al Rehab City
Source: (Talaat Moustafa Group, 2013)
Al Rehab is considering being one of the first housing compounds in New Cairo. It is a
part of New Cairo which contains residential compounds, houses, villas, and world
class five star Hotels and golf courses. The construction of “Al Rehab” was scheduled
in six phases, and was later extended to become ten phases upon it’s completion, each
built on an area of 240 feddans, show figure (3). So It is supposed to offer home to
about 120 000 inhabitants. Other 80 000 inhabitants are expected to find a place to live
in the districts 7-10. All the services needed are provided throughout the city, including
a variety of facilities such as schools, banks, markets and malls (Yousry, A., 2009).

3.1.3. Observation on Al Rehab Case study
The analysis is based on observation in order to reach a checklist to show the relation
of designing of AL Rehab city against the design principles of the sustainable
neighbourhoods. The analysis aims to outline a criteria system for Egyptian
Sustainable Neighbourhoods to minimize it’s environmental impact.
I. Land
A sustainable district ideally integrates housing areas with working spaces
(employment on site), leisure and cultural facilities and services, commercial centres
and services, educational and sports amenities, child care centres and retirement homes
etc. For the case study, it is provided with a variety of services and facilities such as
daily markets, banks, restaurant, schools, parks and recreation areas in proximity of
residential buildings. It has always been distinguished than other gated communities by
its services, running from day one of operation. Figure (4) shows the diversity of land
uses and different facilities within the area, Those facilities and services add to the
attractiveness of the area and reduce the energy needed for commuting to meet the
basic and daily services. This means that this theme is positive and is probably exist in
the neighbourhood design.
Figure (4): Al Rehab land use plan

II. Mobility
Al Rehab is provided by the internal public transportation network. This network
consists from an internal shuttle bus system in addition to buses that transport the
visitors and employment from outside central areas in Nasr City
and Heliopolis districts (Yousry, A., 2009).There are only three lines of public buses to
serve the whole district. There are not enough as they do not cover the whole area of Al
Rehab, which lead to make the private cars is the dominant movement choice.
According to that, it is preferred to increase the bus stations in the neighbourhood with
a maximum distance 250 m from any public transportation. This approximately means
that each neighbourhood should have two bus stations to cover the required walking
distance, and this is essential to be improved by the time in order to increase the
independence of the resident on the public transportation.
Figure (5): Hierarchy of roads within Al Rehab
Source: (Talaat Moustafa Group, 2013, adapted by the author)
Also the internal circulation network of the neighbourhoods gave the priority to private
cars by designing and constructing vehicles’ roads that extend to reach every single
plot and every single building. That ostensibly result in a high percentage of roads,
which have a negative impact on the environment. Those roads were designed with
pedestrian paths allocated along the two sides of the roads. But in fact, the streets do
not have enough shading instruments to encourage the residents to walk or even use the
bicycles, they are dominated mostly by car lanes.
III. Energy
Although energy is one of the most fundamental drivers of social and economic
development in developing countries like Egypt, it does not take the first priority in the
designing of any community. The energy sector and carbon mitigation have to be at the
centre of any sustainable development strategy. Also it has to be at the beginning in
any sustainable neighbourhood plan. In fact, the use of energy, the types of energy used
and the lack of access to sufficient energy have far reaching implications for a city’s
economic development, its environmental health and its social development.
Neighbourhoods which implement sustainable energy and climate action plans to
reduce their vulnerability to energy scarcity and to energy price rises, they have less
traffic congestion and lower energy input costs, they have cleaner air and their low-
carbon economies can afford them a competitive economic edge globally. There is
potential to greatly improve energy efficiencies and reduce carbon emissions in many
upper-middle income developing countries which have a substantial industrial base
(UN-HABITAT and UNEP, 2009).
According to the lack of the passive techniques in Al Rehab design, which negatively
affect the energy consumption in the neighbourhood. There are several steps should be
followed to achieve the energy efficiency in Al Rehab. The first step should be through
applying passive design strategies which will reduce primary energy consumption like:
adding some external shading devices to decrease the impact of the solar radiation, also
improving some elements from the building envelope like windows and the insulation,
which can help in decreeing some of the heat lose inside the buildings. After that, the
second step can be done by optimizing the distribution systems, which will allow a
further saving. Also optimize the building performance by using the smart building
management techniques. Finally, renewable energy sources and actively renewable
strategies that will reduce the primary energy demand (Kellett R. & Fryer S. & Budke
I. , 2009). This is the most expensive, while offering the lowest relative environment-
impact returns. That is why designers should first concentrate on applying passive
design strategies, thereby reducing a large amount of energy demand with little cost,
and only subsequently looked at what active controls could be implemented (UN-
HABITAT and UNEP , 2009). Actually, increasing the initial costs of applying
renewable energy technologies and applying smart technologies will represent a
financial barrier and a technical constraint of turning exiting community like Al Rehab
to increase it is energy efficient, but it can be applied in the future.
IV. Housing
Al Rehab district mainly contains a variety of housing units, it includes villas and
apartment buildings. The development of Al Rehab aimed to accommodate middle
income and high-middle income groups. It offers 52 different prototypes for five story
walk-up building apartments in the development phases. All apartment building areas
are designed in groups, where clusters of building enclose green open spaces,
interconnected together by a pedestrian network that is totally separated from the
vehicles roads and parking lots. For the villas, there are 26 Villa prototypes which
range from 170 square meters including attached, semi-attached and detached villas to
520 square meters in the luxurious ones, all of them with private gardens taking up at
least 60% of the total plot area (Talaat Moustafa Group, 2013). This means that, this
factor is positive and probably exists in Al Rehab neighbourhood.
V. Natural Habitat
This refers to the network of places, ecosystems that support the natural development
of plant and animal populations (Kellett R.& Fryer S. & Budke I. ,2009). This may be
appearing in the green infrastructure network, such as green streets, landscaping
services for both public open spaces and private gardens and adequate vegetation
cover, serves to reduce the heat island effect and adds productive land areas that are
lost by developments. This means that, this factor has intermediate affect in Al Rehab
neighbourhood design.
VI. Economy
This refers to the interplay of jobs and commerce that contribute to the economic well-
being of the neighbourhood (Kellett R.& Fryer S. & Budke I. , 2009). That appeared in
Al Rehab in the Varity of the facilities which include a number of
schools, medical centre and clinics, shopping malls, food court, pharmacies, banks
and office facilities, and workshop area for car maintenance services and specialty
restaurants, recreational services such as the sports club and pharmacies, banks and
office facilities, and workshop area for car maintenance services. All of those
services build a healthy local economy on a diversity of business and employment
options adaptable to change and support the neighbourhood. This means that, this
factor is positive and probably exists in Al Rehab neighbourhood (Talaat Moustafa
Group, 2013).
VII. Food
The on-site food production using domestic conservatories, raised beds, communal
herb gardens, allotments and communal orchards, will guarantee that the biodiversity
of the current site is actually increasing (Kellett R. & Fryer S. & Budke I., 2009). Thus,
this factor does not exist in the neighbourhood. In order to provide on-site food
production in Al Rehab the green corridors through the housing clusters can be used, in
order to form small urban farms which are easily accessible and maximizing the
convenience of growing fresh vegetables and fruit on site from the edible public
landscape planting, also the resident can involve in the greening roof process.
VIII. Water
The sustainable neighbourhood should include a water cycle management plan:
treatment of waste water, reduction of water consumption (equipped with water saving
devices), and implementation of efficient rainwater infiltration systems (Kellett R.&
Fryer S. & Budke I. , 2009). This system is not available in Al Rehab district, so there
is a need to establish this system. Starting with using the water-efficient fixtures which
can be used inside the buildings to reduce water demand, then the waste water could be
reused to flush toilets and irrigate gardens using the gray water system in order to
produce clean or reusable water in the building. According to that, the water system in
Al Rehab needs to be improved in the long run, in order to decrease the rate of
consumption of the water.
IX. Waste
There is a system for garbage collection in Al Rehab district (Yousry, A., 2009), but
actually the neighbourhood should include an integrated waste management plan
consisting of separate waste collection system, incentives for waste reduction and
recycling and minimized building waste. There are different solutions and techniques
can be used like: using the organic waste as fertilizers for the gardens and the
landscaping. Besides the recycling plant should be established near to your community
or inside, so the garbage and solid waste can arrive easily and dally at the plant.
According to that, the waste system in Al Rehab needs to be improved in the long run,
in order to become an integrated waste management plan.
X. Materials
Addressing the environmental impact requires a whole-life approach, involving for any
one material it’s sourcing from nature, its processing, transport, in-use by-products,
recycling and reuse ability, and avoiding its final waste disposal. So whenever possible,
a sustainable neighbourhood is built from natural, recycled or reclaimed materials. This
means that the usage of recycling materials should be encouraged as much as can
(Kellett R.& Fryer S. & Budke I. , 2009). At Al Rehab using recycled materials is not
exit, so the first step should be by using separating waste bins that will make the
separation system of the garbage easy, after that establish a recycling plant near the
community to make the process of the recycling easy and quickly, no need to transport
for a long distance.
3.1.4. The Design Principles
Finally, according to the previous observation the design of the Al Rehab
neighbourhood does not fulfil most of the design principles according to the
environmental aspect of the sustainable neighbourhood, although it considers being one
of the most successful communities of the social and economic aspect. It offers the
model of the lively and livable city. From the resident point of view, it enables them to
feel better about their social and economic status more than the traditional
housing area. It also makes them feel safe and secure, as it protects their children,
keeping out crime, and controlling the quality of services, and prestigious suburban
lifestyle (Yousry A., 2009). Perhaps one of the most important lessons learned from Al
Rehab experience so far is that it is hardly to be considered as a prototype of the
Egyptian communities. Despite being one of the most successful communities of the
social and the economic aspect, it does not consider the best community that uses the
proper design principles to decrease its impacts on the environment. Thus, it was found
from the following checklist that the neighbourhood is suffering from a number of
problems. The following table shows the checklist which explains that the design of the
Al Rehab neighbourhood does not fulfil most of the design principles extracted in the
literature review.
This Checklist will indicate how far the project used sustainable principles:

4. Conclusion
As a result it was proved that the sustainable neighbourhood future is not just an
aspiration. Around the world it is becoming reality as inhabitants, business sectors and
government organizations change their lifestyle to meet the challenges of resource
depletion. In the master plan of sustainable neighbourhood will need to offer integrated
solutions in multiple challenges including design and flexibility to integrate
sustainability techniques. Such techniques should be changed into schemes that study

Need to improve by the time run
construction, implementation and ending from the final phase operation and
management. So this new approach of sustainable communities has become the main
approaches to work towards a more sustainable and an environmental development in
the last few decades. It is the time for Egypt to change the traditional used methods as
the traditional approaches were just schemes with no regard to future changes, and try
to solve all the problems that face the implementation with all means and methods.
New integrated residential neighbourhoods should be attractive places with good
quality and green public space that help create healthy communities. Those residential
neighbourhoods must provide good local infrastructure, transport, water and waste
management. Such provision should be central to our future plans. New growth points
should be put into consideration to improve parks, opens spaces, and greener homes.
Which means that it is not about building more homes, it is about better homes, built to
high standards, both in terms of design and environmental impact and homes that are
part of mixed communities with good local facilities. The new integrated residential
neighbourhoods need to be much more sustainable for the future, as it needs to be part
of the solution to environmental problems not part of the problem. According to that a
revolution in the way of building and designing homes and the neighbourhoods should
be done. It means new skills, supply chains, partnerships and business models,
including for builders and energy suppliers and other stakeholders.
Thus, the good design is fundamental to building according to higher environmental
standards and will play a vital role in getting the most out of new technologies and
approaches, as well as promoting more sustainable patterns of behavior. In addition to
that, the building regulations should be strengthened to set the standards which help to
achieve new sustainable neighbourhoods. Also the architects should integrate
principles of sustainability in designing houses with the surrounding environment in
terms of using climate conditions of the site to achieve the human comfort. That can be
achieved through a proper design for the house (good windows, adequate insulation,
daylighting principles, and efficient heating and cooling equipment) taking into
consideration all the environmental passive design strategies while designing the
house.
